Measure and test the optical properties of photovoltaic cell and module designs using a SPECTRAL EVOLUTION spectroradiometer and RT sphere.

The SPECTRAL EVOLUTION RT (reflectance/transmittance) sphere measures reflectance and transmittance. When used with a portable lab spectroradiometer like the SR-4500, you can test the optical properties of different photovoltaic cell and module designs and coatings. You will be able to see the effects of different materials, coatings, and textures.

To achieve the highest rate of film absorption and subsequent conversion from sunlight to useable electrical energy, different treatments are used including anti-reflective coatings. The effectiveness of these treatments can be measured and compared by measuring a sample’s reflectance, transmittance and absorption using the portable six inch RT sphere with an SR-4500 portable spectroradiometer.

The RT sphere allows you to collect all diffuse light reflected from a sample – measuring total hemispherical reflectance. You can measure reflectance and transmittance and calculate absorption. A specular light trap is included for specular subtraction. The RT sphere is connected to the SR-4500 via an SMA-905 connector. Power can be supplied either independently or form the SR-4500. Sample holders are easy to use and secure for reflectance and transmittance measurements.

The SR-4500 is a high resolution, high sensitivity lab spectroradiometer covering the full UV/VIS/NIR range from 350-2500nm. It uses three thermoelectrically cooled photodiode arrays (one silicon and two InGaAs) to provide the ultimate in performance stability. Like all our spectroradiometers, the SR-4500 includes DARWin SP Data Acquisition software with a pull down menu for solar simulator classification to AM1.0 and AM1.5 and an energy measurement window that calculates integrated radiance or irradiance over a user-determined wavelength band for the spectra of interest. All spectra and associated data are saved as ASCII files for use with third party analysis software.
